How Computers Work: The Evolution Of Technology -

By the 1940s, we entered the era of . These machines, like the ENIAC , were the size of entire rooms. They were revolutionary but incredibly hot, fragile, and power-hungry. 2. The Great Shrink: Transistors and Microchips

Transistors allowed engineers to pack more power into smaller spaces. How Computers Work: The Evolution of Technology

Despite their complexity, computers are actually quite simple at their core. They operate using —a language made entirely of 1s and 0s . 1 (On): Electricity is flowing. 0 (Off): Electricity is blocked. By the 1940s, we entered the era of

The true "big bang" of computing happened in 1947 with the invention of the . This tiny device replaced bulky vacuum tubes, acting as a simple on/off switch for electrical signals. They operate using —a language made entirely of 1s and 0s

The next frontier, which uses quantum bits (qubits) to solve problems that would take traditional computers thousands of years to crack.

The evolution of computers is a story of making things . We’ve moved from room-sized calculators to wearable tech that is millions of times more powerful.

Computers are now being designed to "learn" from patterns rather than just following rigid instructions.
